In this work, we study the temperature-dependent stability of perovskite solar cells and develop a model capable of predicting the lifetime and energy yield of perovskite solar cells outdoors. This model results from the measurement of the kinetics governing the degradation of perovskite solar cells at elevated temperatures. The individual analysis of all key current-voltage parameters enables the prediction of device performance under thermal stress with high precision. An extrapolation of the device lifetime at various European locations based on historical weather data illustrates the relation between the laboratory data and real-world applications. Finally, the understanding of the degradation mechanisms affecting perovskite solar cells allows the definition and implementation of strategies to enhance the thermal stability of perovskite solar cells. | Notes: | [Bastos, Joao P.; Uytterhoeven, Griet; Qiu, Weiming; Paetzold, Ulrich W.; Cheyns, David; Surana, Supriya; Jaysankar, Manoj; Song, Wenya; Aernouts, Tom; Poortmans, Jef; Gehlhaar, Robert] IMEC, Kapeldreef 75, B-3001 Heverlee, Belgium.
